ABSTRACT:
A system for proactive forced renewal of content protection implementations in devices includes a key generation facility to generate and allocate keys for the devices, and to generate revocation data corresponding to revoked keys in response to at least one of a security compromise and on a periodic basis independent of a security compromise; and a device manufacturer to receive the keys from the key generation facility, to embed the keys in content protection implementations for the devices, to distribute the devices, and to renew the content protection implementations in devices after the devices are distributed, in response to at least one of a security compromise and on a periodic basis independent of a security compromise.
